RADIATOR.

Application filed September 17, 1926. Serial No. 136,094.

This invention relates to radiator constructions for the coohng systems ot internal combustion engines, the object of the inven- .tion being to efect increased etliciency of ator core provided with spaced superimposed tins inclined downwardly from front to rear, transversely slotted, and so formed adjacent said slots as to provide downwardly bulging and forwardly facing scoop shaped channels for directing jets of air upward through the slots. The aim of this construction is to divide the air stream into a great number oll angular-ly directed jets, crossing the main stream and impinging against adjacentin surfaces in order to cause..tl1e air to rapidly take up heat from the radiator and to avoid the usual eiect of large quantitiesI of air passing through the radiator without coming into contact with the heat radiating surfaces. vA further aim is to provide in the tin structure a large number of fin sharp or cut edges which rare believed to materially increase the rate of transfer of heat from the fins to the passing air current.

In the accompanying drawings Fig. 1 is a fragmentary front elevation of a sectional radiator core of the general type shown and described in m Sectional radiator Patent No. 1,606,204, issued November 9, `1926, a portion of one sect-ion being shown in section to better show the interior construction;

Fig. 7 is an enlarged section taken on the line 7-7 of Fig. 5. Fig. 8 is a section on line 8--8 of Fig. 1.

The radiator structure illustrated in the drawings comprises vertically extending core sections which are individually and detachably secured by bolts 3 to the upper and 55 lower tanks ot' the radiator and preferably also connected together by bolts 6 extending through lugs or flanges f1 on the side edges ot' core sections. l Y lThe feature of the invention to which this application for patent is ldirected is the lin plate as illustrated in Figures 2 and 3 and in Figures 5 to 7. This is an extremely thin sheet V10 preferably of bronze or copper having its front edge folded backwardly upon G5 itself orotherwise reinforced for strength and good appearance, thus insuring that the insheet will present a straight line at the front of the radiator. This sheet is uniformly apertured t'o receive the water tubes 70 8 and is also lprovided with uniformly spaced transverse slots 13, as shown in Fig. 2. At one side of each slot 13 the tin is depressed by suitable dies to provide scoop shaped deliectors 13. These deflectors serve to direct and permit some ot the air passing through the radiator to be deflected through the slots and projected against the next adjacent 1in plate. 1n this way the air currents through the radiator' are to a great extent divided and 80 caused to brush against or wipe over the heat dissipating surfaces. Since the heat is carried away by convection it is desirable to cause the maximum possible wiping action of the air on the heat dissipating surfaces of the radiator. The etliciency of this particular lin structure is greatly increased by having the fin plates closely spaced and inclined downwardly fromjfront to rear, as indicated in Fig. 4. These scoop shaped depressions in the fins may either face the incoming air, as indicated in Fig. 4, or the reverse.

The usual water tubes 8y which may' be in single or multiple banks, are shown connecting the upper and lower headers 9 of each core section and pass through apertures 11 in the fin plates 10 to which the tubes are scoops adjacent the slots, each scoop being soldered at the flanges 12.` open at the slot end, whereby Sonie of the 10 I claim: air passing along said sheet is most eficiently A radiator fin structure comprising a medirected through said sheet. 5 tallie sheet apertured to receive Water tubes Signed at Racine this 25th day of August,
